What is the largest city in the world? Measured by population and area.


The United Nations estimates the world will reach a total population of eight billion on Nov. 15th, 2022.  With the current population growth, the U.N. also estimates the global population will reach 8.5 billion in 2030 and 9.7 billion in 2050.

The United States Census estimates there are about 331 million people living in the United States alone.  According to Worldometers.com, China with nearly 1.5 billion people has the largest population in the world as of August 2022.

What is the largest city in the world?

  3. Shanghai, China – 26,317,104 people

  9. Beijing, China – 20,035,455 people

What is the largest city in the world by area?

Unlike measuring population, determining the largest city in the world by area is a less straight-forward exercise. Each country has its own definition of what constitutes a city, making a standard measurement for the largest city by area harder to determine. For example, the World Population Review says the city of Sermersooq in Greenland is, by their standard of measurement for a city, over 205,400 square miles for a population of 23,123 people.
